<p>A disk filter, including a plurality of rotatable, axially spaced annular filter disks (6:1-6:11) adapted to be partially immersed in a liquid or a suspension which is to be filtered. Each filter disk comprises a plurality of filter elements (6:1a-f ... 6:11a-f) which are in communication with axial filtrate conduits (2a-2l) arranged at the outer peripheries of the annular disks for discharge of filtrate. For increasing the flow speed of the filtrate in the axial filtrate conduits these slope downwards in the flow direction. This has been achieved in that a filter element (6:1a) of a filter disk (6:1b) is displaced relative to the filter element (6:2a) of the filter disk (6:2) connected to the same filtrate conduit (2a) and being the following filter disk, counted in the flow direction in the axial filtrate conduit, so that the first mentioned filter element is in advance of the later mentioned filter element, as counted in the direction of rotation.</p> |
